The second control is to make the recording part overwrite predetermined data to the RAM bit. The third control is to obtain a second data line from the recording-medium, the second data line being corresponding to a second data pattern of the over-written RAM bit and the ROM bit. The fourth control is to perform an authentication with regard to the recording medium in reference to the first and second data lines.
